Mark,
I think some clubs continue to promote the mystery element in various forms, sometimes conflicting within themselves.
Friar's Head, Merion and Pine Valley come to mind as courses without yardage indicators, however, in some cases, mini-yardage books can be obtained in the pro shop.
I'd like to see more clubs eliminate colored flags, yardage indicators and the other artificial aids that remove the mystery from golf.
Blind holes will always foster mystery.
Yet, as we know, blind holes are unpopular for that very reason, so, I believe that there's a conflict in golf, a clash of the cultures.
Some old line clubs maintain the mystery, rejecting the need to supply the golfer with every possible variant, while others revel in GPS systems, laser range finders, etc. etc..
It's in the culture of the club, and, unfortunately the pressure to provide artificial aids is mounting as more novices, unfamiliar with the history and traditions of golf clamor for their introduction.
End of rant
